FAQ’s

Can I get SMS on my O'Fallon virtual phone number?

Yes, your O'Fallon FlyNumber can receive SMS — incoming texts are forwarded to your email for a small per-segment fee. You can also send personal, person-to-person texts to numbers outside the US — though delivery depends on the receiving carrier accepting texts from US numbers. Texting US numbers is coming soon and will run as A2P, the registered route US carriers require. Full list of SMS enabled numbers here.

Can I use my O'Fallon virtual number for 2FA or other verification services?

This really depends on the company/service sending the SMS to the FlyNumber; it's up to them to actually send the text. We can't guarantee 2FA or short code SMS will work. Texts from regular mobile phones should work fine though.

Can I use FlyNumber to support customers from O'Fallon, even if my business is not based there?

Absolutely! With FlyNumber, you can buy a virtual phone number for O'Fallon and manage your customer interactions from anywhere in the world. This feature is perfect for providing localized customer service or support, akin to having a storefront on Main Street without actually being there.

How can I integrate FlyNumber with devices/software I already use at my office in O'Fallon?

Using FlyNumber, you can make and receive calls on any device — whether it's your smartphone, tablet, or via software solutions like FreePBX or Asterisk.

As a local O'Fallon restaurant owner, can I use FlyNumber to create a call menu for my takeout service?

Definitely! FlyNumber's call menu system is a great tool for managing incoming calls efficiently. You can set up a menu that allows callers to press 1 for today's specials, 2 to place an order, or 3 to speak with customer service. It’s like having a personal assistant, enhancing your customer service.

I run a seasonal business from O'Fallon, can I change my FlyNumber settings depending on the season?

Yes, you can adjust your FlyNumber settings anytime with instant updates, which is ideal for seasonal business fluctuations. Whether it's adjusting to the holiday rush or scaling back during the off-season, FlyNumber gives you the flexibility to manage calls based on your current needs.
